Comparison

Flower also targets federated learning and provides ClientApp, ServerApp, a local Simulation Runtime, and a Deployment Runtime, with a narrower scope. FedML also covers distributed training, model serving, and commercial cloud scheduling. Compare Flower first when the task is to build and simulate a federated strategy. Use FedML for an existing FedML workflow or when its multi-scenario components are required.
